i need to write a shell script..
connecting to another server using ftp and check whether the file ter.txt is exists there or not.
i have written scirpt partially,as i new to Unix.

user $FTPUSER $FTPPW
binary
prompt
${CD}
ls *.txt /home/bin

if you have Python, here's an alternative

import ftplib
server="localhost"
user="anonymous"
password="test@hotmail.com"
def myfilter(line):
     if "ter.txt" in line: print "found: ",line     
try:
    ftp = ftplib.FTP(server)
    ftp.login(user,password)    
except Exception,e:
    print e
else:    
    ftp.cwd("/home/bin")
    ftp.retrlines('LIST',myfilter)
    ftp.close()

Sorry yar,
I don't have python, I need shell script in unxi only.
Thnx

you can use following code:

ssh user@hostname "find . -exec grep -q "ter.txt" '{}' \; -print"

When i used shh command it showing the error as follows.

The authenticity of host 'lpdma523.dev.ipc.us.aexp.com (148.171.30.205)' can't b
e established.

it's not ip addr, can be lcd or any other path on server from where you started ftp session

If you try to connect to other system with ssh it will ask you for authentication. Solution for this issue is creating a trusted host and creating same set of user on both the server. After that you can connect to the other box with ssh username@servername and then execute the script which is required, in your case you execute

cd <location of file>
ls -l | `grep <filetosearch>` >/dev/null

if [ $? ]
then
echo "file exist "
fi

Hi,
i want to search a file existed in another or not using ftp command as follows. When i was using the script there was a problem like data connection is not opened. Please suggest any one..below is text.sh

FTPUSER="user1"
FTPPW="pwd1"
DIR="/home/pbommire/"
CD="cd ${DIR}"
TEMPFILE1="green.txt"
TEMPFILE2="green.txt"
ftp -inv 635.23.33.23> $TEMPFILE1 2> $TEMPFILE1 << EOF
user $FTPUSER $FTPPW
binary
prompt
${CD}
ls -ltr Praveen/test.txt
close
bye
end
echo "Connection success...."
i=`grep -i "test.txt" Praveen/test.txt`
if test "i = "" ;
then
echo "file not found"
fi
